Melbourne police stunned by drink-driving mother and speeding father

Melbourne police say they are shocked after catching a drink-driving mother and a speeding father with young children in their cars.

A woman has been caught driving while more than five times over the legal blood alcohol limit and with her two children in the car.

The 45-year-old blew 0.269 during a random breath test on Beach Road in Sandringham at 9:00pm.

Her six-year-old and eight-year-old children were also in the car.

She will be charged with various traffic offences.

Meanwhile, a man has been caught driving at 200 kilometres per hour in an 80kmh zone in Dandenong South just after 1:30am.

The 44-year-old had his nine-year-old son in the car.

His luxury car has been impounded and he is facing a number of charges.

Inspector Bryan Sharp says it is beyond belief.

"I'm absolutely staggered at what's occurred overnight," he said.

"To find people, particularly a middle-aged lady, at five times over the legal limit with two young children in the car and then on top of that to have a chap driving at 200-plus kilometres an hour in an 80 zone with a nine-year-old boy in the car is just absolutely appalling behaviour.

"I guess from our point of view, it's amazing that people put themselves and other people on the roads at risk with this sort of behaviour, but to actually to put family and friends and in particular children at risk just beggars belief."
